LONDON - After winning titles again on Wimbledon's grass, Novak Djokovic and Serena Williams showed they can cut a rug, too.

Reviving a bygone tradition, Djokovic and Williams busted a move at the Grand Slam tournament's annual champions' dinner, dancing together to "Night Fever," the Bee Gees' disco hit from the 1977 movie "Saturday Night Fever" that starred John Travolta.

"I was very pleased," Djokovic said at a news conference at the All England Club on Monday, a day after beating Roger Federer in the final to collect his third Wimbledon title and ninth at a major. "Serena is a great dancer."

Williams, who won her sixth Wimbledon trophy and 21st at a major on Saturday, tweeted a link to a photo of her and Djokovic at the dinner, and wrote Monday: "congrats @DjokerNole we brought back the dance!"

There used to be a formal ball held each year at the end of the tournament, and the men's and women's singles champions would dance there — but the musical part of the proceedings was discarded decades ago.

Djokovic called it a "tradition that was a bit forgotten," and said he suggested to Williams and the chairman of the All England Club, Philip Brook, that they bring the dancing back.

"They accepted it, fortunately," Djokovic said.

As for the choice of song on Sunday night, Djokovic said: "I was thinking more of a waltz or something, I would say, more sophisticated, something that blends in, in the environment and the beautiful hall where we had the dinner yesterday. But Serena wanted to move a little bit more, so then we considered other options and 'Night Fever' came to life."
